I'm using DAZ Studio 3.0.1.144.  The picture I attached is a screen shot from DAZ Studio, not Poser.

Darn! Next question: are you sure this is an actual asymmetry and not just an artifact of the display? I see that in Poser all the time: in the preview it looks like there's poke-through, but when I actually render, everything's fine.

I'll go through Antonia's rigging again and see if I can find anything fishy, but in the meantime any help isolating the problem would be appreciated. For example: is the asymmetry in the posed figure, the clothing or both?
